You may want to have access to the email, calendar, and address book functionality of Outlook on all your computers, even non-Windows systems such as Mac OS X and Linux. One option is to install Thunderbird on your system (http://www.mozilla.org/en/thunderbird) and use this guide to have it properly set up. All your emails, the calendar, and the address book will then be in sync.
